I believe it that the answer is C. Hope this helps
Smooth muscle cells are contractile and will contract from many different agents such as hormones travelling in the blood and neurotransmitters from the autonomic nervous system. The smooth muscle cells are coupled together so that when one cell contracts, the contraction is relayed to the next. This contractile ability is important in the vascular system as it helps regulate blood pressure by changing the size of the lumen of the vessel.
